This study examined changes in performance in age-group track runners across years from 1975 to 2015 for 100, 200, 400, 800, 1500, 5000, 10 000 m, and marathon and the corresponding sex differences. Athletes were ranked in 5-year age-group intervals from 35-39 to 95-99 years. For all races and all years, the eight female and male finalists for each age-group were included. Men were faster than ...

Vertical distributions of dissolved organic carbon (DOC) were determined in different seasons in the southern Adriatic and Tyrrhenian Seas to study the role of stratification in DOC patterns. These two seas are located at similar latitude but differ in extents of vertical stratification. Stratification affects DOC dynamics in both basins, but with interesting differences. In the Tyrrhenian Sea,...

the aim of the present study was to evaluate hypnotic effect of coriandrum sativum, ziziphus jujuba , lavandula angustifolia and melissa officinalis hydroalcoholic extracts in mice to select the most effective ones for a combination formula. three doses of the extracts (250, 500 and 1000 mg/kg of c. sativum and z. jujuba and 200, 400 and 800 mg/kg of l. angustifolia and m. officinalis ) were or...

A new compound, MK800-62F1, was isolated from a cultured broth of Streptomyces diastatochromogenes MK800-62F1. The structure was determined by NMR analysis and degradation experiments.

We developed a new surface-selective time-resolved nonlinear spectroscopy, femtosecond time-resolved electronic sum-frequency generation (TR-ESFG) spectroscopy, to investigate ultrafast dynamics of molecules at liquid interfaces. Its advantage over conventional time-resolved second harmonic generation spectroscopy is that it can provide spectral information, which is realized by the multiplex d...

Abstract The scarcity of freshwater has attracted the attention countries around world. Capacitive deionization (CDI) is a burgeoning ElectroSorb Technology with low price and high efficiency. It important for CDI to prepare electrodes inexpensive adsorption capacity. efficiency depends on properties electrodes. In this paper, porous carbon materials derived from corncobs, cornstalks, waste cig...
